Bone Density


A CT Bone Density scan (QCT) is an accurate way to diagnose osteoporosis and decide your risk for a future fracture. Two different machines that measure bone density are DEXA and QCT (Quantitative Computed Tomography). QCT is a more accurate method of following a patient’s bone density over time. However, patients should not switch back and forth between QCT and DEXA. Once a patient and their doctor choose QCT Bone Density analysis, future exams should also be performed with QCT, as the results will be a more accurate comparison of the patient’s true bone density changes over time.

QCT is a three-dimensional method obtained on a CT scanner that provides true bone density of the spine and hip. DEXA bone mineral density estimates may be significantly biased by severe degenerative changes of the hip or spine, vascular calcifications, oral contrast agents (from other radiology exams), and foods or dietary supplements containing significant amounts of calcium. QCT is also often more accurate in patients with obesity.

QCT targets the trabecular bone (the first to show changes of bone loss) and measures it separately from the surrounding cortical bone, degenerative changes, bone spurs and vascular calcifications, which can mask osteoporosis in many patients.


Before your Exam

Please wear loose fitting comfortable clothing.

To ensure the quickest results, please advise our schedulers of any prior ultrasound imaging that has been performed at a different facility.

Plan to arrive at least 15 minutes before your appointment to allow time to process your registration. Your technologist will greet you and take you to a locker room to change if needed.


During your Exam 

Your exam will be completed under CT. You will be positioned on our CT table by your technologist and lay still for approximately 10 minutes.


After your Exam

Once your exam is complete it will take about 24-48 hours to be faxed to your doctor. If your doctor has access to our online PACs system results are available within 24 hours unless we are waiting on outside priors.

Our goal is to make this experience as comfortable as possible for you while acquiring the information needed to provide your doctor with adequate results. Thank you for trusting us with your scan.
